HEATING METHOD OF MATERIAL TO BE TREATED AND HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To clean waste gas by catalytically reacting a decomposition gas treated in vacuum or a non-oxidation atmosphere with a reaction chemical in the same state as that of the decomposition treatment to convert to a harmless compound to substitute. SOLUTION: Reaction vessels 31a, 31b of a reaction treatment means 30 are filled with one kind of the reaction chemical reactive with a harmful material in the decomposition gas and is tightly closed. A non-oxidation atmosphere furnace 10 and the reaction vessel 31a are communicated with each other through a pipe line P1 and a connection pipe 33 and the reaction vessel 31a and the reaction vessel 31b are communicated with each other through a connection pipe 34. A vacuum pump 32 is connected to the reaction vessel 31b and the decomposition gas generated in a rotary cylindrical body 12 provided in a vacuum vessel 15 is passed through the reaction vessels 31a, 31b by operating the vacuum pump 32 to catalytically react the reaction chemical with the harmful material to convert to the harmless compound to substitute and is sent to a bag filter 41 of an exhaust means 40 and discharged from a stack 42.
